Example: An employee is sick for 11 "consecutive" days from October 1 through October 11, meaning that each day in the period October 1 through October 11 is a day of sickness and there is no day in that period that is not a day of sickness. If the employee also had days of sickness on October 16, 17, 18, 21 and 22, those five days are considered "successive" days of sickness.
